React Shifts Development Mindset with Hooks

Most React developers ignore this until their app starts crashing randomly. I recently debugged a frontend issue that didn’t show up in logs, didn’t throw errors… but quietly killed performance over time. Turned out — it was a memory leak in useEffect.

🚀 React Series – Day 12 useCallback – Preventing Unnecessary Function Re-creation In React, functions are re-created on every render by default. In many cases this is fine, but when passing functions to child components, it can cause unnecessary re-renders. The useCallback hook helps by memoizing functions - so the same function instance is reused unless dependencies change. This is especially useful when working with optimized components (like memoized ones). 👉 In simple terms: • useMemo → memoizes values • useCallback → memoizes functions Used together, they help keep applications efficient and performant. #reactjs #javascript #frontenddeveloper #webdevelopment #codinginterview #learnreact #30daysofcode #programming #reactinterview #react #coding

Hey everyone ☺️ Going back to the basics and brushing up my React fundamentals. No matter how many advanced tools and libraries we learn, strong fundamentals always make the biggest difference. Right now, I’m revisiting these core topics: • JSX • Components • Props • State • useState • useEffect • Conditional Rendering • Lists with map • Event Handling I believe that when your fundamentals are strong, building scalable and clean applications becomes much easier. Advanced concepts feel less confusing when the foundation is clear. Sometimes, the best way to grow is not only by learning new things, but also by strengthening what we already know. #React #JavaScript #FrontendDevelopment #ReactJS #LearningJourney #Programming #SoftwareDevelopment #Coding #SoftwareDevelopment #LearningJourney

🚀 React Series - Day 10 Avoiding Unnecessary Re-renders with React.memo As applications grow, performance becomes more important. One common issue is unnecessary re-rendering of components. This is where React.memo helps. It is a higher-order component that memoizes a component - meaning it will only re-render if its props actually change. If the props remain the same, React skips rendering that component, improving performance. 👉 This is especially useful for components that: • Receive the same props frequently • Are part of large or complex UIs Used correctly, it can make applications faster and more efficient. #reactjs #javascript #frontenddeveloper #webdevelopment #codinginterview #learnreact #30daysofcode #programming #reactinterview #react #coding

This is where 90% of React devs lie to themselves. “I know hooks.” No—you don’t. Because if you did: - your components wouldn’t re-render like crazy - useEffect wouldn’t feel like black magic - and you wouldn’t be “optimizing” things that were never slow This isn’t a React problem. It’s a 𝗺𝗲𝗻𝘁𝗮𝗹 𝗺𝗼𝗱𝗲𝗹 𝗽𝗿𝗼𝗯𝗹𝗲𝗺. You’re not thinking in React. You’re trying to control it. And React always wins that fight. Fix how you think → everything else gets easier. Be honest— Which hook still trips you up the most? #reactjs #webdevelopment #frontenddeveloper #softwaredeveloper #javascript #codinglife #programming #reacthooks #devcommunity #learnincode

3 React hooks you should use more often: 🔹 useMemo Caches expensive calculations. Recalculates only when dependencies change. 🔹 useCallback Caches a function reference. Prevents unnecessary re-renders in child components. 🔹 useReducer Better than useState for complex state logic. Think of it as a mini Redux. Most devs only use useState and useEffect. The ones above can make a real difference. 🎯 #ReactJS #Frontend #JavaScript #WebDev #Programming

🚀 React Series - Day 1 Why Everything in React Starts with Components At its core, React is all about components. Instead of building one large UI, React encourages breaking everything into smaller, reusable pieces - like buttons, headers, cards, and sections. This approach makes applications: • Easier to manage • More reusable • Cleaner to scale Modern React mainly uses functional components, which are simple and powerful when combined with hooks. #reactjs #javascript #frontenddeveloper #webdevelopment #codinginterview #learnreact #30daysofcode #programming #reactinterview #react #coding

Master Modern JavaScript in One Glance JavaScript has evolved a lot, and writing clean, efficient code is no longer optional—it’s essential. From let/const to Promises and destructuring, these modern features help you write more readable, maintainable, and scalable code. If you're still using older patterns, it's time to upgrade your approach and level up your development game.
